Low Energy Positive Input Ventilation Unit Installation and Maintenance
IMPORTANT NOTES TO INSTALLERS
The FLATVENT range has been curing severe condensation problems for
over 20 years in some of the worst affected properties throughout the world.
Its successful operation depends entirely upon the unit being installed strictly
in accordance with these instructions. We would, therefore, respectfully
suggest that you read through this guide in its entirety before commencing
installation and then go through this guide step by step to ensure a
satisfactory completion.
Whilst the installation of the Flatvent unit may be achieved by a suitable
craftsman, the provision of the electrical supply and the connection of the
unit to the mains must be carried out by a qualified electrician.
The unit has a 5 year warranty starting from the day of delivery and includes
parts and labour for the first year. The remaining 4 years covers parts only.
This warranty is conditional on the following:-
a) That the unit is installed strictly in accordance with this guide.
b) That the unit filters are removed and cleaned or replaced at the
recommended intervals.
The unit represents a significant financial outlay on the part of the
user/specifier and the unique 5 year warranty is important to them. We make
a point of advising them that the installer is provided with detailed
instructions regarding installation/guarantee registration and therefore has
the responsibility of ensuring that the unit is guaranteed for the user/specifier.
1.0 INSTALLATION
The unit is designed to take fresh air from outside, clean the air, warm it (if fitted
with heater) and discharge it into the central hallway via a system of ducting
supplied by the installer. The dwelling internal air discharge grille is usually
installed at high level in a central location within the hallway, although
discharging the air down the length of the hallway (away from the front door)
should also prove acceptable. Unit performance may be enhanced if an existing
heat source can warm the discharged air eg. by locating the discharge grille
above a radiator.
Before commencing installation decide the best position for the unit and where
the fresh air input air is to come from and be discharged to. The unit can be
installed in many different configurations and is supplied with enough
interchangeable spigots to enable it to be used with either round (100mm) or
rectangular ducting (121mm x 60mm). The unit can be turned through 180o to
any angle if required.
Figure 1. (above) Typical installations show unit with top discharge.
FIXING THE UNIT TO THE WALL
The unit has four mounting pads. Mark through these pads when the unit is in
the correct position. Drill and plug wall with suitable fixings. Remove PCB cover
and feed the electrical supply cable through the grommet hole (standard
1mm three core lighting cable is recommended) in the rear of the unit screw
unit to wall.
POINTS TO CONSIDER
1. The inlet ducting should be kept as short as possible to avoid
condensation build up on the ducting surface (see figs 5/6).
2. Can the discharge grille be located to take advantage of existing
heat sources?
3. Find the shortest, most direct route from outside of the unit and then to
the discharge grille using the least number of bends (these bends
increase the airflow resistance).
4. Note the location of any joists, pipes, electrical cables etc.
5. Allow adequate access to the front cover to allow filter cleaning?
6. Refer to the relevant Building and Electrical Regulations.
DATASHEET
Where the systems are installed in flats where regulations require the provision of a
protected entrance hall or protected enclosure and the outlet of the systems are
within that enclosure it is necessary to ensure that the safety of the enclosure is not
compromised either in relation to its fire resistance or the entry of smoke. Smoke
detectors must be connected to the fan so that it shuts down if smoke enters the
ductwork. Ductwork must be of steel, with the point of fire penetration stopped, or if
non fire-resistant ducting is used, it must be protected in fire-resisting construction
up to the point where it penetrates the wall of the protected entrance hall or
protected enclosure. Where the systems are installed in flats where these regulatory
provisions do not apply, good installation practice should be observed; for example
the use of smoke detectors to control the fan, to ensure that occupant safety levels
are not reduced. For more information please refer to the Building Regulations,
Approved Document B (Fire safety) – Volume 1: Dwelling houses (2006 Edition)

FITTING THE DEFLECTOR PLATE
Fit deflector plate into scroll cover as shown below. Once fitted the assembly
can be slotted into the scroll and clipped firmly in place.
TRANSFORMATION PIECE
This should be on the appropriate scroll outlet. The transformation piece
should be fitted into the chosen outlet spigot insert, prior to fitting.
Note: If the round spigot is used as an outlet, the 115 x 55mm clear blanking
plate will need to be fitted (as shown). This plate should be prevented from
movement by the use of silicone sealant.
INLET/OUTLET GRILLE INSTALLATION
If a flyscreen is fitted it should be removed from both the internal and
external grille.
Note: When installing the internal grille, the louvres MUST SLANT
UPWARDS to ensure the correct air circulation and the avoidance of
unpleasant downdraughts. The outside wall input grille louvres MUST
SLANT DOWNWARDS.
Standard 100mm dia ducting or 121 x 60mm ducting is used to connect the
Flatvent to the input and discharge grilles.
FIXING ALL NECESSARY DUCTING
A full range of ductwork and ductwork ancillaries are available. Please contact
Flatvent for further details.
2.0 HEATER OPTIONS (ORDER CODE FLAT-HEATER)
The heater kit contains a blank insert with a cut out for the switch. This blank
can be fitted into any appropriate opening. It is important that the switch is
fitted so that the terminals are at the bottom.

4.0 SETTING THE UNIT
The speed selector is located on the PCB (see bathroom application figure 11)
The unit has a choice of three speeds to suit the size of the dwelling and the
moisture being generated.The unit is factory set at No 3. We recommend that
the unit is operated at this speed and the setting reduced if and when
necessary in the future.
Replace PCB cover and test the unit. Check rotation of fan with diagrams
under airflow direction. If direction is incorrect, isolate the unit, remove PCB
cover and alter the rotation switch (mounted on the PCB). Replace PCB cover
and re-check direction of fan. Replace filter and front cover.
INSTALLATION AND MAINTENANCE Low Energy Positive Input Ventilation Unit

Q. What is a Flatvent Home Improvement Unit?
A. It is a small wall mounted, air cleaning/moving device that continuously
inputs filtered fresh air into the dwelling from outside.
Q. What does the unit do?
A. The unit will cure and/or prevent the problems associated with
condensation in your home, providing a cleaner, healthier living
environment for all occupants. The unit will prevent mould growth on
walls, ceilings, furniture, clothes and curtains. The unit also eradicates the
musty smells evident in homes with severe condensation problems.
Q. How does it work?
A. Simply and very efficiently. Outside air is drawn into the unit, filtered and
then ducted into a central area (typically the hallway/ stairwell) of the
dwelling. However, the performance of the unit may be enhanced if an
existing heat source can be mixed with the discharged air. For instance,
the unit could be mounted to discharge into an airing cupboard. The
cupboard would then have an outlet grille fitted in the top of its sidewall
to supply tempered air into the dwelling. As the air is supplied into the
dwelling it mixes with the warmer air that naturally accumulates at ceiling
level taking advantage of the heat from this warm air you have paid for
but are not making use of. This tempered, fresh, clean air then
continuously and gently dilutes, displaces and replaces the air within your
home. The result is a home free from serious condensation and a more
pleasant and comfortable environment.
Q. How much does it cost to run?
A. When you consider the advantages the unit will provide for you and the
other occupants, the running costs are insignificant. However, it should
be remembered that the unit is making use of heat at ceiling level that
would otherwise be lost.
Q. How do I operate the unit?
A. You don’t have to. From the time the installer starts the unit it will run
continuously for many years of trouble free use.
Q. What maintenance is required for the unit?
A. Very little. The only maintenance required is the removal and cleaning of
the filter every 12 months to 2 years. (The filter can also be vacuum
cleaned).
Q. How will I remember to clean the filters?
A. When the filters become dirty, the unit does not input as much air into
the dwelling. Condensation and musty smells may become evident.
This will be a signal for you to check and clean or replace the filters
as necessary.
Q. How will I know if the unit is working?
A. The unit motor may be almost inaudible but you should notice a change
of atmosphere in the hallway within a day or so. ‘Within a few weeks any
mould should start to dry out and eventually become a grey powder
which can easily be cleaned. After a month your home will be a healthier
environment free from severe condensation dampness and probably
more efficient.
Q. What do I do if the unit stops working?
A. If the unit appears to have stopped operating please contact our:
If you are a Housing Association or Local Authority tenant however, you
should contact your Local Housing Office in the first instance.
UNITS FITTED WITH HEATER
Some units are fitted with a heater to temper the incoming air. A heater neon
indicator switch (normally mounted on the side of the unit) is provided on
these models. You can choose when you wish to use the heater.
The installation must only be examined by a qualified electrician and must
always be isolated before an inspection. Under no circumstances must the
unit be dismantled as this will invalidate the warranty.
OPTIONAL HOUR RUN MONITOR
This simple plug in device monitors the number of hours the unit has been in
operation. It will start from the moment the monitor is plugged in and the
unit switched on (refer to figures 8 and 9).
5.0 MAINTENANCE
The only maintenance required is the removal and cleaning of the filter every
12 months to 2 years. (The filter can also be vacuum cleaned).

IMPORTANT
Any air intake terminal MUST be installed in accordance with the appropriate
regulation. As a guide, the BS5440 series of British Standards deals with this issue and
currently states that an air intake must be at a minimum distance of 300mm from a
gas boiler balanced flue. Installers are advised to be aware of the requirements of this
standard when installing ‘through the wall’supply air ducting. Similarly, supply and
extract air grilles should be at least 300mm apart.
